The document describes the Konno-Rastan aortoventriculoplasty procedure for congenital heart disease. The procedure involves making a vertical incision in the aorta and extending it into the right ventricular outflow tract. The aortic valve is then excised and the interventricular septum is incised to enlarge the aortic annulus. An aortic valve prosthesis is secured within the enlarged annulus. A Dacron patch attached to the prosthesis sewing ring closes the interventricular septum and aortotomy. A separate pericardial patch closes the right ventriculotomy.
8. • The Konno-Rastan aortoven-
triculoplasty permits significant
enlargement of the aortic annulus and
subaortic region
• A. A vertical aortotomy is made to the left
of the right coronary artery and extended
into the right ventricular outflow tract.
• After excising the aortic valve, the
interventricular septum is incised and an aortic
valve prosthesis is secured within the enlarged
annulus.
• B. A Dacron patch that is attached to the
sewing ring of the prosthesis closes the
interventricular septum and the aortotomy.
• C. A separate peri-cardial patch closes the
right ventriculotomy
